    Our Service

    Adding Space to Launceston Homes Since 2009

    Launceston's housing stock is built to last — and for many owners, that means a home with great bones and not quite enough space. Whether it's a growing family needing another bedroom, a couple wanting to expand the living area, or a home office that needs genuine separation from the house, a well-designed extension is often more cost-effective and far more rewarding than uprooting and moving to a new property.

    Davies Design & Construction provides end-to-end extension services across greater Launceston, the Tamar Valley, and surrounding areas. Our design-build model integrates Align Architecture & Interiors — our in-house architecture firm, founded by Luke Davies — with our construction team. Design and construction briefed together means one accurate cost from the start, not a design fee followed by a painful repricing at tender.

    From adding a rear living extension to an Invermay cottage to building a contemporary second storey on a Riverside family home, Davies brings architectural integrity and construction precision to every project. We design extensions that feel like they were always part of the house — not additions that advertise their own arrival.

    We also bring Passivhaus-informed performance thinking to every extension. An addition is an opportunity to dramatically improve the thermal performance of your whole home. With proper insulation, double glazing, and airtightness, a Davies extension will set a new standard for comfort in your home — warmer in winter, cooler in summer, and quieter year-round than the rooms around it.

    What We Build

    Extension Types We Build in Launceston

    Single-Storey Extensions

    Rear and side extensions that expand the ground floor — new living rooms, bedrooms, kitchens, or utility spaces. The most common extension type in Launceston, offering maximum impact for the investment.

    Second Storey Additions

    Adding a full second storey or partial upper level dramatically increases floor area without expanding the footprint. Ideal for narrow Launceston blocks where garden space is valued.

    Studio & Granny Flat Additions

    Self-contained studio, home office, or secondary dwelling — attached or separate. Adds rental income potential, multi-generational living flexibility, or dedicated work-from-home space.

    Deck & Verandah Extensions

    Outdoor rooms that genuinely extend your living space — covered decks, wrap-around verandahs, and alfresco areas designed for Launceston's climate and your home's specific character.

    Building Envelope Upgrades

    Super-insulation, airtightness, and double glazing improvements that transform how every room performs. Often combined with an extension to lift the whole home's thermal standard in a single project.

    Heritage Home Extensions

    Sensitive additions to heritage-listed and character homes across Launceston's historic precincts. We work within Tasmanian Heritage Council requirements while delivering modern space and performance.

    Local Knowledge

    Extending in Launceston — What You Should Know

    Launceston's planning environment has specific factors that affect extension projects. We surface these early so there are no surprises mid-project:

    • Planning permit thresholds: Extensions that stay within the Tasmanian Planning Scheme's Permitted development standards — covering setbacks, height, and site coverage — don't require a full planning permit. We identify which category your project falls into before the design process begins.
    • Heritage overlays: Significant parts of inner Launceston, South Launceston, Newstead, and the Trevallyn heights fall under heritage overlay zones. Extensions in these areas may need a heritage impact statement and design modifications. Our Align team is experienced in designing within these constraints.
    • Asbestos in pre-1985 homes: If your project requires structural alterations to existing fabric in a pre-1985 Launceston home, asbestos identification and safe management is a legal requirement. We factor this into the feasibility assessment before any commitment.
    • Terrain and slope: Launceston's gorge-facing slopes in Trevallyn, the elevated Riverside sites, and the steeper ground in South Launceston can affect structural approach, retaining requirements, and extension cost. A proper site assessment early prevents costly changes later.
    • Drainage and services: Extensions adding wet areas or changing drainage patterns require plumbing sign-off. Older Launceston homes often need drainage upgrades at the same time — we identify this during the design and pre-construction phase, not mid-build.

    Weighing extension against knockdown-rebuild? Our Launceston area guide covers building costs, land values, and planning considerations across the greater Launceston area. Our main Renovations & Extensions page covers the full scope of what Davies provides statewide.

    Common Questions

    Launceston Extensions FAQ

    How much does a home extension cost in Launceston?+
    Home extensions in Launceston typically range from $2,500 to $5,000 per square metre of new floor area, depending on structural complexity, site access, and finish level. A single-storey ground floor extension of 30–50m² generally costs $90,000–$180,000. A second storey addition is typically $150,000–$350,000+, given the structural and staircase requirements. Davies provides a detailed cost assessment as part of our feasibility process — before any commitment is made.
    Do I need council approval for a home extension in Launceston?+
    Most structural extensions in Launceston require a planning permit from Launceston City Council and a building permit. Extensions that fall within the Permitted development standards of the Tasmanian Planning Scheme — covering setbacks, height, and site coverage — may not require a full planning permit. Heritage-listed properties and properties within heritage overlay zones require additional heritage approvals. Davies manages all permits and planning processes as part of our service.
    Does Davies build home extensions in Launceston?+
    Yes. Davies Design & Construction and Align Architecture & Interiors provide a complete extension service — from architectural design through council approvals to construction — across greater Launceston, the Tamar Valley, and northern Tasmania. We specialise in extensions that genuinely feel like they belong with the original house, not additions that announce themselves as afterthoughts.
    Can you extend a heritage home in Launceston?+
    Yes, though heritage extensions require particular care. Many inner Launceston suburbs — including the heritage overlay areas of South Launceston, Trevallyn, and inner city precincts — are subject to Tasmanian Heritage Council requirements. Our design team at Align Architecture has experience designing extensions for heritage-listed and heritage-character homes in Launceston, creating additions that are sympathetic to the original building while delivering modern performance and liveability.
    What types of extensions does Davies build in Launceston?+
    We build single-storey rear and side extensions, second storey additions, deck and verandah extensions, studio and granny flat additions, garage conversions, and open-plan reconfiguration projects across greater Launceston. Our design-build approach means your architect and builder are the same team — which eliminates the pricing surprises that come from designing first and pricing later.
